interrupting violence with "don't shoot"

npr | In 1985, David M. Kennedy visited Nickerson Gardens, a public housing complex in south-central Los Angeles. It was the beginning of the crack epidemic, and Nickerson Gardens was located in what was then one of the most dangerous neighborhoods in America.

"It was like watching time-lapse photography of the end of the world," he says. "There were drug crews on the corner, there were crack monsters and heroin addicts wandering around. ... It was fantastically, almost-impossibly-to-take-in awful."

Kennedy, a self-taught criminologist, had a visceral reaction to Nickerson Gardens. In his memoir Don't Shoot, he writes that he thought: "This is not OK. People should not have to live like this. This is wrong. Somebody needs to do something."

Kennedy has devoted his career to reducing gang and drug-related inner-city violence. He started going to drug markets all over the United States, met with police officials and attorney generals, and developed a program — first piloted in Boston — that dramatically reduced youth homicide rates by as much as 66 percent. That program, nicknamed the "Boston Miracle," has been implemented in more than 70 cities nationwide.

Today, Kennedy directs the Center for Crime Prevention and Control at John Jay College of Criminal Justice in New York City, but he still regularly goes out into the field. The drug world he works in now, he says, is a little better than the one in which he worked in 1985 — but not by much.

"Still, it's almost inconceivably awful in almost all of its dimensions," he tells Fresh Air's Dave Davies. "And no one likes to say this stuff out loud, because it's impolitic, but the facts are the facts. You get this kind of drug activity and violence only in historically distressed, minority neighborhoods. And it is far worse in poor, distressed African-American neighborhoods."

Those neighborhoods are also more likely to be deadly for African-American men — and they're getting worse, says Kennedy, citing grim statistics: Between 2000 and 2007, the gun homicide rate for black men between the ages of 14-17 increased by 40 percent. The rate for men over the age of 25 increased by 27 percent. In some neighborhoods, 1 in 200 black men are murdered every year.

"This is where the worst open-air drug markets are all concentrated," he says. "And quite naturally, law enforcement pays an awful lot of attention to those neighborhoods. ... And the shorthand that you get from cops when you look at these communities is that they look at you and say, 'There is no community left.' "

But there are plenty of law-abiding residents in these neighborhoods that have been overtaken by drugs, says Kennedy. They outnumber the gang members and drug dealers by significant percentages.

"What matters is that these offenders are in the communities in groups," he says. "They are in gangs, they are in drug crews, they are in chaotic groups. And those groups drive the action to a shocking degree."

In Cincinnati, for example, there are about 60 defined gang groups with about 1,500 members.

"[The people] representing less than half a percentage point of the city's population are associated with 75 percent of all of Cincinnati's killings," he says. "And no matter where you go, that's the fact."

The national homicide rate is now about 4 per 100,000, but the homicide rate for members of gangs and neighborhood turf groups is dramatically higher: as many as 3,000 per 100,000 a year.

"It is incredibly dangerous," says Kennedy. "If you talk to these guys, what they say is, 'I'm terrified ... I got shot ... My brother's dead ... I've been shot at ... And they are trying to shoot me ...' That [is] their everyday world."
